Patented Apr. 19, 1932 UNITED STATES JI'OHNQ. NORTON, 011 SAN FRANCISCO,GAIJIORNIL wnnnnws noon Application filed October 11, 1930. Serial 110.488,128.

My invention relates to improvements welders hoods, audit consists inthe combinations, constructions and arrangements hereinafter describedand claimed.

An object of my invention is to provide a welders hood in which an eyeshield section is movable in the plane of the front face of the hood bya chin-actuated means for un covering the eye opening in the front face.

The glare shield is held in raised position by means of a weightedtrigger, and the operator can free the trigger from the shleld by movinghis head abruptly in a lateral direction, whereupon the shield will dropmto closed position by gravity.

A further object of my invention is to provide a device of the typedescribed which is simple in construction and which dlsposes the darkglass on the inside of the hood and the protecting glass on the outsideof the hood.

Other objects and advantages will appear as the specification proceeds,and the novel features of the device will be particularly pointed out inthe claims hereto annexed.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a section along the line 1-1 of Figure 2, 0

Figure 2 is a front elevation of the devlce, and

Figure 3 is a rear elevation.

Tn carrying out my invention 1 make use of a standard hood indicatedgenerally at 1 and having a front .face 2. The hood is supported uponthe head of the operator by a headpiece 3.. The parts thus far describedare standard in construction and form no part of my invention exceptinsofar as they cooperate with the partsnowto be described.

The front face 2 has an opening 4 which is disposed at the level of theoperators eyes.

A glare shield indicated generally at 5 is slidable across the opening 4and isconstructed in the following manner.

An outer member 6 is slidable on the outer face of the portion 2 of thehood, and this member has flanged edges 7 for reinforcing it. y The sideflanges 7 slidably engage with guides 8 that are secured to the face 2.The

bottom flange 7 rests against a stop 9 which is also secured to the face2.

The piece 6 is secured to a U-shaped member 10 that is disposed on theinner face of the part 2.and is spaced from the piece 6 by a U-shapedspacing member 11. The outer sides of the member 11 bear againstthesides of the opening 4 and guide the glare shield 5 in its movement. y

The glare shield carries glasses which cover an opening 12 in the piece6. A dark glass 13 is disposed on the inside of the glare shield and issecured to the U-shaped member 10 by side clips 14 (see Figure 3) and abottom clip 15. A clear protecting glass 16 (see F igure 2) is disposedon the outside of the glare shield 5 and is secured to the piece 6 byside clips 17 and a bottom clip 18. These glasses are removable so thatnew ones can be sublowermost position with the exception of the opening12, and this opening is covered by the glasses 13 and 16. V The meansfor raising the glare shield 5 vertically is shown in Figures 1 and 3.19 are pivoted to the U-shaped member 10 and are disposed beyond thesides of the glass 13 so as not to interfere with the vision. These armsare connected to levers 20 that are pivoted at 21 to a support 22, thelatter being secured to the inner face of the part 2. Links 23 aresecured to the inner ends of the levers 20 and have their other endssecured to an enlarged end 24 of a pull rod 25. The rod 25 is guided ina sleeve 26 that is carried by the support 22. p

An adjustable chin rest 27 is carried by the along a rack 28 formed inthe rod 25.

I also provide means for supporting the .glare shield 5 in raisedposition, and this comprises a weighted trigger. 29 (see Figure '3)pivoted at 30 and having a cam edge 31 and a top edge 32. A pin 33 iscarried by the glare shield 5, and the upward movement of the shieldwill cause the pin 33 to engage with the cam edge 31 and swing thetrigger 29 in a clockwise direction about its pivot 30. The

triggerwill swing back into the position shown in Figure 3 when the pin33 clears the edge 31. A freeing of the glare shield 6 w' now cause itto move downwardly until the pin 33 rests upon the top edge 32. Thetrigger 29 will now support the glare shield in raised position. 4

From the foregoin description'of the various parts of the dev1ce, theoperation thereof may be readily understood.

i 10 The hood ad usted on the operators head in the usual manner, andthe chin rest 27 is raised so as to lightly contact withthe chain of theoperator. Theweight of the glare shield 5 will hold it in closedposition,

16 and the operators eyes will be protected by the lasses 13 and 16.

Vhen the operator wishes to raise the glare shield, he moves the chinrest 27 downwardly, and this, through themechanism already de- 20scribed, raises the glare shield and uncovers the lower part of theopening 4, The operator can now check the work. The trigger 29 supportsthe glare shield in raised position as long as the operator desires.

. In-releasing the glare shield, the operator moves his head abruptly ina lateral direction, which causes the weighted trigger 29 to move in aclockwise direction about the pivot 30 and to free the pin 33. The glareshield 30 5 will now drop into closed position by avity.

4 Although I have shown and described one embodiment of my invention, itis to be understood that the same is susceptible of 3 various changes,and I reserve the right to employ such changes as may come within thescope of the claims hereto annexed.

I claim: 1. The combination with a welders hood 4 having a front facewith an opening for the eyes therein, of a glare shield normallycovering the opening, chin actuated means for sliding the shield alongthe hood surface into open position and comprising arms pivoted to thesides of the shield, levers connected to the arms, links connected tothe levers, and a bar connected to the links and having a chin supportextending beneath the chin.

2. The combination with a welders hood having a front face with a sightopening therein, of a glare shield normally covering the opening, meansfor moving the shield in the plane of the front face of the hood foruncovering the opening, a member engage- 5 able with the shield forholding thelatter in open position and being releasable from engagementwhen the hood is moved abruptly in a lateral direction.
